Lenovo IdeaPad 320 SODIMM Upgrade

This 16GB DDR4 module is built for the Lenovo IdeaPad 320-14KBL, 320S-15AST and 320S-15ABR. It targets owners of those laptops who need the maximum single-stick capacity the platform allows. The part number C107 confirms the matched specification.

260-Pin Unbuffered Non-ECC Build

The stick uses a standard 260-pin SO-DIMM edge connector with no heat spreader, so it slides into the single memory slot without clearance issues. Unbuffered, non-ECC chips at 1.2V keep power draw low for mobile battery life. Major-brand components are used throughout.

Replaces Lower-Capacity Factory Memory

Most IdeaPad 320 units shipped with 4GB or 8GB; this module doubles or quadruples that space in one step. The jump is worth it when the system slows under multitasking or when 8GB is no longer enough for current workloads. Buyers who need more than 16GB total cannot use this platform.

Questions about this item

What DDR4 speed and PC4 rating does this SODIMM run at?

This module operates at 2400 MHz with a PC4 19200 data rate, matching the DDR4 2400 standard used by the IdeaPad 320 series.

Which SODIMM slot and pin count does this 16 GB stick require?

It uses a standard 260-pin DDR4 SO-DIMM slot; the IdeaPad 320-14KBL, 320S-15AST and 320S-15ABR each provide one such slot for this upgrade.

How do I install the module and what step is often missed?

Power off the laptop, remove the bottom cover, align the notch on the 260-pin stick with the slot key, press firmly until both side clips click, then reassemble — forgetting to seat both clips is the common mistake.
